摘要: The aim of this study was to evaluate the effects replacing Tifton-85 hay (0, 20, 40, 60 and 80 % on a dry matter basis) with water hyacinth (Eichhornia crassipes) intake digestibility nutrients, feeding behaviour, rumen blood parameters sheep. Five uncastrated male sheep, cannulated in rumen, an average body weight 40 kg were assigned 5 × 5 Latin square design. contained 870 g/kg (DM), 159 g/kg crude protein (CP), 547 g/kg neutral detergent fibre (NDF) 461 g/kg total digestible nutrients (TDN). DM NDF non-fibre carbohydrates (NFC) linearly reduced by hay. Similarly, there linear reduction rumination time efficiencies NDF. concentrations urea, glucose, AST GGT plasma not changed Although some replacement could be economically advantageous for sheep feeding.
